I am not usually adding any photos of the week / month, but for this theme I have the perfect photo already on wikitree!
My grandfather Kalle loved music, photography and technology. He became an electrical engineer, but kept his other interests as hobbies.
Here he is in 1929 with his band on stage, probably practising.
Kalle plays the piano. The names of the others are unknown to me.
According to hearsay, the band name was Pagan Love Band.
